Genesis 3:1, 24

Now the serpent was more cunning than any beast of the field which the LORD God had made. And he said to the woman, “Has God indeed said, ‘You shall not eat of every tree of the garden’?”

So He drove out the man; and He placed cherubim at the east of the garden of Eden, and a flaming sword which turned every way, to guard the way to the tree of life.
